Hello Doctor, Hope you all are doing well. My wife is facing some fertility Issue and got to know that her egg reserves is less. We consulted a fertility centre last month and she was provided with some medications like Letroze and coenzyme tablets. At last visit doctor provided Mephrate tablet for 15 days and informed to come back after 15 days to do biopsy. Unfortunately her periods got delayed by 10 days and now again after her last cycle she got periods in 10 days. Does that happen? Using Me phrate tablet had this effect of periods coming with in 10 days? Will it continue in this way? Appreciate your help.
